I recently bought a sheet of high-density polyethylene (HDPE) for making some model scenery. The trouble I had is that it came in a 1" thick sheet, and I only wanted to make a base for a model. I tried various methods for carving a chuck of the HDPE thinner, but either ended up with cut fingers or a messy, rough and uneven finish on the base. Enter the hot-wire cutter. I hadn't had much success with these things in the past, as they take a bit of getting used to, and I didn't think I'd be able to hold the thin sheet of HDPE, hold the cutter and at the same time smoothly push the HDPE through the cutter. The simple solution was to make a poor-man's hot-wire bench-cutter! Simply place the cutter so that it's firmly secured to something (okay, I just layed it on the table) with the wire horizontal and level above a second surface. The second surface should be adjustable, which in my case meant placing paper/books/scraps/etc under it to reach the correct height. The absolutely key thing here is to push the part through the wire firmly and smoothly. If you hesitate at any point, the heat from the wire will melt right through the part - it doesn't have to be touching it! Try it out on a scrap first, the cutter takes a bit of getting used to, when you first apply the part to the wire, it cuts through it very quickly due to the heat built up, once you're going though, you'll feel some resistance and it's much easier to judge.
As usual, get all your supplied of HDPE, wood, basing-materials, and all other modelling supplies from the 4D Modelshop.
